These mesmerizing maps show just how noisy your city can be

If you live in a major city, you're probably used to some
background noise.

Still, some streets are noisier than others, whether that's
because they're close to transportation hubs like airports or
there's just a lot of construction in the
neighborhood.

Online real estate platform Trulia enlisted the help of
CartoDB to create maps that
show the noisiest neighborhoods in New York City, San Francisco,
and Seattle. The animated maps show the frequency of noise
complaints across the city over a five-year span, starting in
December 2009 and ending in June 2015.

The maps light up with yellow for each noise complaint and become
red as complaints become more frequent in a particular
area.

They're mesmerizing to watch. Here's a look at New York
City, where noise complaints appear to be fairly evenly
distributed.

In San Francisco, the noisiest residents appear to
be concentrated in the Tenderloin, the Upper Haight, and the
Mission.

And in Seattle, Capitol Hill and the University District
get the most noise
complaints.
